Sepfile

A SEPlib file object SEP.sepfile.sep_file is built from one to three SEP.args.basic objects (history file, header format file, and grid format file). You can access the collection of parameters directly through the history, headers, and grid objects (e.g. sep.history.par("n1")). In addition it has the concept of axes and keys (if the data is SEP3D and possesses headers). You can get the number of dimensions, retrieve and set axes (n,o,d,label,unit) and keys (name,format,type), and return the size of the dataset.
